2-dimensional silica-silica Continuous Fiber-reinforced Ceramic.matrix Composites (CFCCs) were fabricated by a sol-gel infilitration method that has a changing processing condition, such as the repetitions of infilitration. In order to investigate the relationship between the processing condition and the mechanical properties of composites, the mechanical properties of specimens were measured by means of a 4-point flexural strength test while the evidence of strength degradation were microstructurally characterized. There seemed to be a minimum density value that existed at which the delamination between the fabrics would not occur. In the case that the density of silica CFCCs exceeded 1.55 g/cm3, the flexural strength also exceeded approximately 18 MPa at least. By applying the Minimum Solid Area (MSA) analysis of the porous structure, the correlation between the relative density and the mechanical properties of composites will be discussed.

The wheat-rye translocation lines have been agriculturally developed for the resistance to the biotypes of Hessian fly as a major insect pest of wheat. In order to compare the proteomic profiles between ‘Coker797’ (non-2RL), ‘Hamlet’ (2RL), and near-isogenic line (NIL) carrying 2RL, we evaluated the protein extraction and preparation methods for two-dimensional gel electrophoresis approach. The tissues such as leaves, stems, and roots from three wheat-rye lines were extracted by following trichloroacetic acid (TCA)/acetone precipitation. In a preliminary proteome analysis, a commonly expressed protein in Hamlet and NIL strain was identified as methionine synthase annotated in Hordeum vulgare subsp. The present study will provide the experimental guideline for the proteomic study of other useful crop plant tissues.
